Product Description

Festo QS-8-4 Pneumatic Reducer Nipple provides a compact, robust solution for connecting pneumatic tubing in automated and industrial settings. The push-in design allows for quick and secure connections, facilitating efficient installation and maintenance in complex pneumatic systems.

The reducer nipple offers a transition from an 8 mm inlet to a 4 mm outlet, supporting compatibility with standard pneumatic tube sizes. Nitrile rubber (NBR) seals ensure leak-free performance, even in environments exposed to oil-based lubricants. The nickel-plated finish protects the steel and brass elements from wear, chemical exposure, and corrosive agents commonly encountered in factory and processing plants.

Maximum operating pressure of 14 bar supports high-pressure applications in automation, food processing, and laboratory settings. Wide temperature tolerance from -10°C to 80°C allows use in refrigerated and heated spaces.

Certified food grade, making it suitable for food contact and hygienic installations. Meets DIN 73378, FDA, ISO 8573-1:2010, RoHS, DIN 5510-2, and UL (QS-V0) approval for global compliance. Chemical-resistant design increases operational lifespan in chemically active environments.

Typical use cases include automated actuator connections, instrumentation for electronic assembly, pneumatic conveyance and control in food processing plants, and workshop tool hookups. With reliable sealing performance, this fitting is well-suited for both lubricated and non-lubricated compressed air operations.

Its compact profile and advanced material construction make the Festo QS-8-4 fitting an excellent choice for manufacturers, laboratory engineers, and industrial automation specialists needing dependable pneumatic connectors.
